I have made numerous purchases from the Wool Room, including wool pillows, Merino Fleece mattress enhancer and the latest purchase a Deluxe Wool Topper. All their products are excellent quality and delivered very quickly. I would say perhaps worth purchasing a slightly larger topper than your mattress size if you can. I purchased the exact same size in the Merino Fleece enhancer and rather than stretch I found it bunches slightly and pulls in on the sides. Whereas I purchased the next width up for the Deluxe Wool Topper and it is much better and stays in place, appears like the photographs and goes slightly over the edge of the mattress.
